Raptors' Jakob Poeltl: Won't return due to back tightness

Poeltl (back) has been ruled out for the rest of Sunday's game against the Nets, Vivek Jacob of the Raptors' official site reports.

Poeltl was cleared to return Sunday after a two-game absence due to a back injury, but he appears to have aggravated the issue during the first half. Sandro Mamukelashvili should start in the second half and see a significant increase in playing time in Poeltl's absence.
